Within any enterprise, video files are the largest and most bandwidth-intensive assets that need to be distributed. And video distribution technology has a significant impact on overall user experience and engagement, with studies showing that viewers will begin abandoning videos if content doesn’t begin streaming within as little as two seconds.

With this in mind, the Qumu Video Engagement Platform provides the most diverse, flexible and robust set of solutions for enterprise video delivery available today—intelligently selecting the video delivery method that optimizes the viewing experience for each location, end-user and endpoint device. At the heart of Qumu’s solution is an intelligent business rules engine and CDN broker known as Pathfinder, which allows organizations to simultaneously utilize any or all of the multiple live and on demand delivery options listed below.


Caching involves storing on demand video content on multiple servers (called Media or Edge Servers) across the network—meaning Caching only applies to on demand video and not live video. When a video is requested by a user, it is automatically stored locally on an Edge Server so that other users in that region or network area may access it. Caching greatly reduces the number of times a single video asset is pulled across a WAN, which both accelerates video delivery and reduces bandwidth usage.

External CDN

External Content Delivery Networks (CDNs) such as Akamai, Amazon CloudFront, Level 3, and Cloudflare are paid services that utilize the internet to deliver video. While not a distribution technology in and of itself, an external CDN can be beneficial as part of the distribution mix in certain use cases. External CDNs allow organizations to offload video traffic from an internal network, and can be a great way to deliver video to remote users on VPN connections or in branch offices with local internet connections.


Multicast involves streaming live video from a Source Media Server to a group of secondary hosts or recipients on a network. A good analogy would be a radio broadcast—the server simply “broadcasts” a video signal, and whoever wants to tune in may do so. The biggest advantage of multicast is that it minimizes WAN traffic because requests for video assets are not being sent across the network.

Peer-to-Peer (P2P)

Peer-to-peer distribution allows devices on the network—like two employee laptops, for example—to connect and share video directly from one to the other. P2P is gaining momentum in the enterprise as of late with the emergence of WebRTC, which allows video to be shared directly between browsers without apps or plugins. Peer-to-Peer can significantly minimize WAN traffic, because the video asset is being streamed from a peer instead of a Source Video Server. P2P is also especially useful in companies with many branch offices, where it is impractical to deploy Edge Servers at each location.


Unicast distribution is the simplest form of streaming video within an enterprise—sending video from a single media server directly to a single recipient. Unicast is a simple, mature and reliable technology requiring minimal configuration, and is also supported natively by most network devices. To use Unicast successfully in high-volume environments, most companies will also deploy Edge Servers at key sites to ensure video is served as locally as possible.

Virtual Desktop Infrastructure (VDI)

VDI is a technology used by many large enterprises to give mobile and thin client devices a centrally controlled set of applications and data—such as a Citrix solution—and therefore a standardized end-user experience. VDI optimization allows companies to offload video traffic from the Citrix server to an Edge Server, which not only dramatically minimizes WAN traffic but also makes “desktop equivalent video” possible for thin client and mobile devices.
